Buffy the Vampire Slayer - Angel matou quando ele tinha uma alma?

Em 1898, Angel tem sua alma retornada como parte de uma maldição:

You don't remember. Everything you've done. For a hundred years. In a moment, you will. The face of everyone you have killed — our daughter's face — they will haunt you and you will know what true suffering is

Ter sua alma devolvida encoraja Angel a ser um "bom rapaz", por exemplo,

1996: The reclusive and emotionally tortured Angel was sought out by a demon named Whistler, who persuaded him to join the fight against the evil that had corrupted him and to help the newly-activated Slayer, Buffy Summers. Angel traveled to Hemery High School in Los Angeles, where he witnessed Buffy being called as the Slayer and her initial training under her Watcher, Merrick, as well as her emotional suffering over her new duties and her parents' deteriorating marriage. Filled with a new purpose in life, Angel resolved to help the Slayer, with whom he had fallen in love, and moved to Sunnydale, California, where Buffy was predestined to move the following year

No entanto, em S3 E10, o Primeiro Mal provoca Angel com os rostos das vítimas do passado, incluindo um empresário, Travis, que foi morto em 1998 .

A minha pergunta é, como Angel é capaz de matar inocentes apesar de ter uma alma?

N.B. Angel também matou os filhos de Travis, então a defesa de 'talvez Travis fosse mal' não funciona aqui.
